Ghost equivalent for Linux?

Greetings.
I'm currently looking for a Ghost equivalent for Linux.
My goals are fairly simple:
* Live backups
* Quick and easy restores
* Ability to backup across the network (like a laptop, for example)
* It would be cool if I could do this stuff command line.
* While I'm being picky, let's add cheap to the list :-)

It's also very possible that I won't be restoring to the same computer,
so backing up / is my goal.

I'm running my own personal server, so this isn't something corporate.
I run a few domains as a hobby and I'm paranoid something nasty will
happen (because I'm tin foiled like that).
I've seen MondoRescue however it seems to have problems still (perhaps
it's too young).

I plan on making 650MB iso images (if possible) and burning them for a
quick restore.

I see Acronis as a possible option, but I couldn't tell if it had a
Linux binary.
I've heard of using dd, however I have a bit of paranoia on the
restoring part.
I've started a 'dd if=3D/dev/hda3 | bzip2 -5 > /mnt/samba/backup.img' but
that seemed to take a long time and I fear that I won't be able to
restore to a different sized partition (apparantly resizing an ext3
partition is a dangerous thing and not very reliable -- or at least the
many docs I've found and tried -- scared the crap out of me when I
couldn't mount / and had to run e2fsck to get it back in working order).

I had set up Amanda in the past on a server using a 7TAPE DAT drive the
network also had several PCs that I had to backup.

It is a little confusing but if you sit down with it and start simple
then add in the complexities it is not that bad. To backup a PC you
will need to have SAMBA (reverse mapping available) a share on the drive
that you have rights to (this can be configured) and it all works fairly
well... It took me about a week to set it up and that was about 7 -8
years ago... I really ahve not played with it since. I am sure there
has to be some good documentation on how to set it up.
